Thunderbolt All-Purpose Anchors Hexagon Head ZYP - M12 x 100

The one and only Thunderbolt™ is the original and best-selling general purpose all-metal anchor with the power to be used on a whole range of construction materials including concrete, concrete block, brick, and stone. It is a one-piece, non-expansion anchor, meaning that it does not require a wall plug or resin, and therefore makes it ideal for close-to-edge fixing applications. The threaded anchor and self-tapping action allow for safe anchorage, with the substrate becoming the nut to the bolt.

• Hexagon head.
